IMPROVEMENT EN CUPBOARD-CATCHES.

Specification forming part of Letters Patent No. 132,721, dated November5, 1872.

To all whom it may concern:

Be it known that I, J osErE OTTNEE, of N ew Britain,.in the county ofHartford and State of Connecticut, have invented certain Improvements inCupboard -Catches, of which the following is a specification:

My invention consists of the peculiar construction of the latch-Wiz., alatch with a concentric and eccentric face, and pivoted upon a pin andprovided with an operating handle which extends from the concentricface, as hereafter shown and described 3 and, second, ofthe combinationot'said latch with the spring and case having a box and concentric flangesall as herein set forth.

In the accompanying drawing, Figure l is a front elevation of acupboarddatch which einbodies my invention, and Fi g. 2 is a horizontalsection of the same on line rc x ot' Fig. l.

A designates the latch-case5 B, the striker; C, the latch proper; and D,its handle. Inside of the case A is a box or barrel, a, (see Fig. 2,) in`which I secure the latch C by means of a pin, b. From the pin b to thepointcthe edge of the latch C has an eccentric face, which "may beeither in a straight or curved line.

The front edge of said latch, from the point c to the handleV l), I formconcentrically With the pin I). The remaining portion of the latch isalso concentrically formed, but it may be of other form, if desired. Twoconcentric flanges, d d, are formed on the front of the case A, theedges of which anges are about even with the front edge of the latch C.A spiral spring, n, is placed With one end resting in the corner of thebox c and the other end upon a projection formed on the latch, as shownin Fig. 2.

To release the latch from the striker it is only necessary to press thehandle l) to the right, when the latch oscillates on the pin l) anddisengages from the striker B. In closing the door the striker engageswith the eccentric face of the latchthat is, the portion between the pinb and point c-throws it back, and allows it to pass said striker, whenthe spring a throws it into the position shown in Fig. 2. In case theconcentric portion of the latch is forced outward against the striker itWill force the latch more tirml y into it instead of releasing ittherefrom.

By my invention I produce a cupboard-catch Which is simple inconstruction, is easily and conveniently operated, can be produced at asmall cost, and is very compact, operating Well in a case less than aninch long, so that it is admirably adapted for use on sash-doors.

I claim as my invention- I. The latch C, with -its concentric and eccentric faces meeting at the point c when said' latch is pivoted uponthe pin l), and is provided with the handle D extending outward from theconcentric face, all substantially as described.

2. In combination With the foregoing the spring u and case A, the latterprovided With the box a and concentric flanges d d, all substantially asand for the purpose described. JOSEPH OTTN ER.
